SkyFan™ was originally conceived around proven GE turbine power, but the fully FAA-certified GE Catalyst is now the stronger long-term choice. Although Catalyst’s certification timeline extended SkyFan’s development path, the result is a modern clean-sheet turboprop engine that better aligns with SkyFan’s efficiency goals. GE Aerospace states that Catalyst was designed to deliver 15% better fuel burn, 10% more power at altitude, and integrated FADEC control that gives pilots a simplified, jet-like single-lever operating experience. For SkyFan™, that means improved specific fuel consumption, stronger high-altitude performance, more available power, and a cleaner path toward efficient, reliable business-aircraft operation.
